采用常规深度处理工艺处理东太湖原水，对比砂滤前置与后置对各工艺流程出水消毒副产物生成潜能去除效果的影响。研究发现，无论砂滤前置还是后置，生物活性炭工艺对有机物都有着良好的去除效果，整套工艺出水COD和UV254的去除率分别稳定在74.2％～87.1％和75.0％～80.2％。两套工艺对二甲基亚硝胺生成潜能（NDMAFP）的去除效果没有明显差别，出水NDMAFP降低35％～41％。砂滤前置工艺对三卤甲烷生成潜能（THMFP）和卤乙酸生成潜能（HAAFP）的控制效果优于砂滤后置工艺，砂滤前置工艺活性炭单元出水和砂滤后置工艺砂滤单元出水的THMFP分别降低31.0％～37.4％和28.2％～

The difference of pre-sand filtration and post-sand filtration in the formation potential of disinfection by-products for East Taihu Lake water by conventional-advanced treatment process were investigated and analyzed. The investigation shows that the biological activated carbon has a good effect on removal of organic matter regardless of pre-sand or post-sand filtration and removal rates of COD and UV254 of effluent maintain 74.2% ~87.1% and 75.0% ~80.2%,respectively. No significant difference on removal effect of NDMA formation potential (NDMAFP)is found comparing two sets of treatment processes and removal rate of NDMAFP of effluent is 35% ~41%. The pre-sand filtration process shows a stronger removal capacity of trihalomethane formation potential (THMFP)and haloacetic acids formation potential (HAAFP)removal than post-sand filtration. Removal rates of THMFP of effluent in pre-sand filtration and post-sand filtration are 31.0% ~37.4% and 28.2% ~35.3%,respectively. Removal rates of HAAFP are 20.0% ~24.6% and 16.3% ~23.2%,respectively.
